Some people just dont want to waste they irl money on a game.
You know that making a game is a work. So they need money. I mean if you say that i can say to a man in a shop. "Please give me this i don't want to waste my money". No there's not wasting it. They waste it like in their book, clothes, activites. Would you say that to somebody that want to get like a book for free ?
PS: Sorry, for my bad english
I know that irl it doesn't work well, yet to have more clients you have to make the prices less expensive. There are a lot of other ways to also get money anyway. To get models etc. it's not easy, but if they could make a free game in itch.io and google play, then it wouldn't be really really hard to make a full game, since all the models and stuff are done.
ps : I'm bad at explaining so dw😉
